This product was previously sold as Amazon Collection and is now part of the Amazon Essentials line. It is a timeless 1/3 cttw sterling silver necklace featuring a two-tone twisted infinity pendant encrusted with black and white round diamonds 9.6mm in width and 28.3mm in length on an 18" rolo chain. The round white diamonds are I-J, I2-I3, 0.13 carats, and the round black diamonds are 0.20 carats. The total carat weight is 0.33 carats.

The necklace has an 18" rolo chain with a lobster claw clasp. It is plated with an anti-tarnish coating and should be stored in a cool, dry place in its own container or compartment, with limited exposure to extreme temperatures, perfume, and household cleaning products.

No two diamonds are alike. A diamond's most distinguishing characteristics are its inclusions, marks that are often invisible to the naked eye. However, under a jeweler's magnifying loupe or microscope, they can look like crystals, tiny rivers, or clouds. A diamond's clarity is determined by the presence or absence of inclusions--fewer inclusions mean better clarity--and how visible they are. The greater a diamond's clarity, the greater its brilliance and value.

Though diamonds come in a wide range of colors, colorless diamonds have traditionally been considered the most valuable. Most diamonds are graded on a scale using the letters of the alphabet, from D (colorless), the best grade, through Z (a light yellow). It is difficult for the untrained eye to notice such variations in color unless stones are being compared side by side.

A diamond's weight is measured in carats, with one carat being equivalent to 100 points. Larger stones are often more highly valued, but size should not be the only consideration--high brilliance, which varies according to clarity, cut, and color grade, is highly desirable in a diamond.
